The Walmart Onn 4K Plus has quietly become one of the most popular budget streaming boxes for UK IPTV viewers, and the reason is simple: Google TV, a built-in Ethernet port, and full sideloading freedom for under £40 (after import). Paired with TiviMate, it turns into a serious cable-replacement experience that competes with devices three times the price. This guide walks through the full install, the Xtream Codes login, the EPG and catch-up settings that actually matter, and the small tuning steps that keep 4K UK sports feeds buttery during peak windows.
Why the Onn 4K Plus Is the Sweet-Spot Device for TiviMate in 2026
The Onn 4K Plus (and its newer sibling, the Onn 4K Pro) sits in an unusual spot in the UK market. Most cheap streaming boxes either lock you to a manufacturer app store (Roku, Apple TV) or run a heavily skinned Android build with no sideloading (older Smart TVs). The Onn runs near-stock Google TV with full Play Store access and full sideload support — exactly what TiviMate needs.
Three hardware details matter for IPTV specifically: a 100 Mbps Ethernet port that eliminates Wi-Fi contention during 4K streams, hardware decoding for AV1 and HEVC that keeps power draw low on long sports sessions, and enough RAM that TiviMate's multi-view and large UK channel lists run without stutter. None of those are guaranteed on a sub-£40 device.
Onn 4K Plus Specs UK Buyers Should Know
Before you order, confirm you are getting the model that supports the workflow in this guide. The 'Plus' label has been used on more than one Walmart unit over the past three years; the current generation (also marketed as 'Onn 4K Pro' on some listings) is the one to target.
Google TV, near-stock, with Play Store access. Full sideloading is supported via Downloader and the Android Debug Bridge.
4K HDR up to 60 Hz, Dolby Vision, HDR10+. Enough for 4K UK sports and 4K VOD libraries.
Built-in 100 Mbps Ethernet (the key differentiator at this price), Wi-Fi 5, Bluetooth 5.0 for the voice remote and game controllers.
32 GB internal — more than enough for TiviMate, a backup player like IPTV Smarters Pro, and a couple of utility apps.
Voice remote with a Google Assistant button. Once configured, saying 'open TiviMate' launches the player without touching the channel grid.
Before You Start: Three Things to Get Ready
A NovaVisonIPTV subscription or trial — your Xtream Codes credentials (server URL, username, password) delivered by WhatsApp or email. Request the free 24-hour trial here if you do not have credentials yet.
A Google account already signed in to the Onn 4K Plus during initial setup — this is required to install Downloader and TiviMate from the Play Store.
A wired Ethernet connection if possible. Wi-Fi works, but UK ISP throttling during Saturday 3 PM kickoff is materially worse over Wi-Fi than over a wired connection.
How to Install TiviMate on the Onn 4K Plus Step by Step
Configuring Xtream Codes API for NovaVisonIPTV on TiviMate
TiviMate's Xtream Codes login is the standard way to connect to NovaVisonIPTV and is what gives you a full premium IPTV experience on the Onn 4K Plus. The credentials you receive from NovaVisonIPTV are a single set; you do not need to subscribe twice for TiviMate and a backup player.
If your credentials reach you in a format like http://server.example:8080/get.php?username=USER&password=PASS&type=m3u_plus, you can still use them as Xtream Codes — TiviMate will parse the URL into server, username, and password fields automatically. If you prefer to enter them manually, the server portion is everything before /get.php (including the http:// and the port), the username is the value after username=, and the password is the value after password=.
Save the playlist with a clear name like 'NovaVisonIPTV UK' so that when you add a backup playlist later, you can switch between them with two clicks.
EPG, Catch-up, and Multi-View Settings That Matter
TiviMate's defaults are good but not optimised for UK IPTV. These five settings make the biggest difference on the Onn 4K Plus.
Settings → EPG → Channel sources. Leave it on the playlist's built-in EPG unless you have a specific override. NovaVisonIPTV's EPG includes UK terrestrials, sports, and the major catch-up programming.
Set to every 6 hours overnight, not on app launch. This avoids a 10–20 second delay each time you open TiviMate.
Settings → Playback → Catch-up. Enable it and set the default look-back to 'maximum'. UK channels with catch-up will then show a small clock icon in the EPG grid for any replayable programme.
Settings → Playback → Buffer. Default is 1 second. Increase to 3–4 seconds for 4K UK sports — it smooths out the small throttling spikes UK ISPs introduce on Saturday afternoons.
TiviMate Premium adds split-screen for up to four streams. On the Onn 4K Plus you can comfortably run two 1080p streams or one 4K + one 720p without dropped frames.
Tips for Smooth 4K UK Sports on the Onn 4K Plus
The Onn 4K Plus is more than capable of running 4K UK sports streams, but the streams themselves are the bottleneck — UK ISPs throttle aggressively during live windows, and shared international servers buckle. Three changes make the largest practical difference.
The biggest single uplift in stability. Wi-Fi 5 is fine for VOD; Ethernet is the difference between freezing at 67 minutes of a Premier League match and not.
NovaVisonIPTV's UK-focused servers and anti-block routing are designed for exactly the Saturday 3 PM window. Shared international panels are not.
The Onn 4K Plus hardware-decodes AV1, which uses less bandwidth than HEVC at the same quality. If your provider streams AV1 4K (more common in 2026), it will be smoother.
Onn 4K Plus vs Firestick 4K Max for IPTV in 2026
For UK households deciding between the two best budget IPTV devices, the differences come down to ecosystem and connectivity.
Built-in Ethernet, near-stock Google TV, full Play Store TiviMate installation (no sideloading required), AV1 hardware decoding, lower long-session power draw.
Easier UK availability, Alexa integration if you already use it, more first-party UK app support (BBC iPlayer, ITVX, All 4, My5 all preinstalled).
If you watch a lot of live sport over IPTV: Onn 4K Plus, every time, for the Ethernet alone. If you mix UK terrestrial catch-up with IPTV on the same device: Firestick is slightly more convenient day-to-day.
Common Issues and Fixes
TiviMate says 'Playlist URL is invalid'. Double-check the server URL — including the http:// or https:// prefix and the port number. The most common cause is missing the port or pasting the URL with hidden whitespace.
Channels load but no EPG appears. Wait the full 90 seconds for first sync. If still empty, Settings → EPG → Refresh now. If still empty, the EPG source may have moved — message support on WhatsApp and they will send the current URL.
4K UK sports buffer after 10 minutes. Switch to Ethernet, raise buffer to 4 seconds, and confirm your provider has UK-dedicated servers — not just an international panel with a 'UK section'.
TiviMate crashes on launch. Almost always a corrupt cache after an app update. Onn 4K Plus Settings → Apps → TiviMate → Clear cache (not 'Clear data', which removes your playlist). Relaunch.
Voice remote does not open TiviMate. Google Assistant needs a one-time 'TiviMate' shortcut. Open Google Assistant from the remote, say 'open TiviMate', and approve the action when prompted. Subsequent launches work without confirmation.
Frequently Asked Questions
Can I buy the Onn 4K Plus in the UK?
Not directly from a UK retailer — Walmart does not ship to the UK. UK buyers source it through eBay, Amazon UK marketplace sellers, or international forwarders. Total landed cost in 2026 is typically £35–£50.
Do I need TiviMate Premium?
TiviMate is free with a single playlist and basic EPG. TiviMate Premium adds multi-playlist support, multi-view, advanced EPG features, and external player integration. For a single-provider setup on the Onn 4K Plus, the free version is fully usable; for two providers or multi-view, Premium is worth it.
Do I need a VPN with TiviMate on the Onn 4K Plus?
A VPN is not legally required in the UK, but it is strongly recommended for any IPTV use in 2026 because UK ISPs throttle streaming traffic during live sports. A provider with strong anti-block routing — like NovaVisonIPTV — reduces but does not eliminate the need.
Can I use other IPTV players on the Onn 4K Plus?
Yes. IPTV Smarters Pro, IBO Player Pro, OTT Navigator, and others all install from the Play Store. TiviMate is the most polished, but having a second player installed as backup is good practice — if one app stalls during a live event, the other reads the same Xtream Codes credentials.
Which UK channels work?
All UK terrestrials (BBC One, BBC Two, ITV, Channel 4, Channel 5 and their HD/regional variants), Sky Sports, TNT Sports, Sky Cinema, kids, news, documentaries, and the major international channels. The full current lineup is on the NovaVisonIPTV channel list page.
Is the Onn 4K Plus better than the Firestick 4K Max for IPTV?
For live sports — yes, mainly because of the Ethernet port and AV1 decoding. For mixed catch-up and IPTV use — close, with the Firestick slightly more convenient because of preinstalled UK apps. See the comparison section above for details.
